SPECIFICATION forming part of Letters Patent No. 465,510, dated December22, 1891.

Application led February 2, 1891. Serial No. 379,872. (No model.)

To @ZZ whom it may concern:

Be it known that I, CHARLES O. YALE, of New York, in the county of NewYork and State of New York, have invented certain new and usefulImprovements in Safes or Vaults; and I do hereby declare thatthefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the figures of reference marked thereon, which form part of thisspecification.

My invention relates to improvements in safes or vaults and doors andoperating and Vlocking mechanism therefor. l

The particular features of this invention consist in providing a safe orvault doorcapable of a vertical and swinging movement, to the end thatthe floor-of vault may be on the same level with the door on outsidewithout any hinderance or obstruction in the passage-way into the vault,or that the door or safe-tioor and lower jamb or threshold may be in thesame plane, and also in the devices for handling and securing the doorto accomplish these results.`

In the drawings which accompany and form a part of this speciication,and in which similar figures of reference refer to corresponding partsin the several figures, Figure 1 shows the outside front of a vault-doorand one construction of hangings therefor. Fig. 2

shows the same parts shown in Fig. 1 from locking the door; but thisparticular systemv of bolt-workY is not essential. Fig. 5 shows asection of vault body and door in first stage of opening. Fig. 6 is adetail view relating to particular locking-bolts.` Fig. 7 shows side andedge elevations of a pair of cog-gears used in the construction. Fig. 8is a detail figure showing a side, top, and end elevation of aneccentric and connection.

Referring more specifically to the referencenumerals marked on thedrawings, 1 indicates the body of the Vault, having an opening adaptedto receive door 2. The door-jamb at top and sides recedes by offsets orsteps from the front inward, as shown at 3, and is preferably providedalong the sides and across the top with a groove or recess 4, adapted toreceive a tongue 5 on the door. At the bottom the door jainb or sill isprovided with one or more grooves or recesses 7 7, tbc., adapted toreceive corresponding tongues' 6, &c., on the bottom of the door.Secured ,to the door near the top is a hanger-block 8, to which arepivoted at 8a hinge-connection pieces 9 9, which are pivoted at 9 attheir upper ends to ear 10 on crane-arm 11. Arm 11 forms ya part ofcrane 12, which crane is hinged so as to slide vertically on the piutlesof hinges 13 and 14, fixed on the jamb. On the crane l2 is provided alifting-lug 15, 'providedwith an adjusting-screw 15a, under which screwengages arm 16. Arm 16 is connected with arm 17by a joint, and forms, inconnection with arm 17, a knucklefjointf Arm 17 has bearing at itslowerend in a hinge-like projection 18 on the door-jamb.

19 is a lower projecting arm forming part of crane 12 `and providedlwith set-screws 2O and 21, which extend to and are adapted to engageagainst the face of the door 2. Connected to the knuckle-joint by aconnectingrod 22 is an eccentric 23, mounted upon a shaft24, having abearing in the crane-arm 12. which is meshed by gear 26on the inner endof shaft 27. Shaft 27 has bearing in crane 12 and has hand-wheel 28mounted on its outer end.

Secured on shaft 24 is a cog-gear 25,

Firmly secured on the inner face of the t the bottom screw-threadedlocking-bolts 31, working through suitable screw-threaded openings inthe bolt-bars. The bolts 30 are connected to throw-bars 35 in anyofseveral well-known manners, and the throw-bars are connected together tosecure simultaneous movement of the bolts, as by connecting-rods 32 andpivoted disks 33, pivoted to the door at 34. To the lower pivoted disk33 is connected by connecting-bar 3G throw-bar 37 of the screwebolts3l.- The screw-bolts 3l are provided with very steep threads, (see Fig.6,) and the head of the screw locking-bolt 31 is provided with anencircling groove, in which IOO the throw-bar 37 engages, so that thebolt 31 moves laterally with the throw-bar, but rotates independently ofit. The bolt 3l engages within suitable screw-threaded openings in thebody of the safe. On the inside of the door and mounted upon a spindleeX- tending through the door and provided with an operating-handle 38 onthe outside is disk 39. In disk 39 is provided a pin 40, which engages`in a slotted opening in throw-bar 35,

so that the door is unsecured, by rotating hand-wheel 28 in eitherdirection through the intermediate connecting-gears, shafts, andeccentric, knuckle-joint arms 16 and 17 will start i to fall into thesame line and the weight of the door istaken on the lug and the arms 1-6and 17. As soon as the weight is thus taken the connecting-arms 9, beingon an incline, swing the ldoor from the position shown in`- Fig. 3outward until the upper end of the door strikes against arm 11,whenbycontin-uing the rotation of thewheel 2 8 until the knuckle-joint haslmade its full throw the door israised until the tongues and grooves atthe bottom become disengaged, as shown in Fig. 5. In this posi-tion thedoor is carried free by the crane on arms and is free to be swung open.It is preferable that the adjustment of the knuckle-joint shall be suchthat when the tongues and grooves at the bottom of the door becomedisengaged the arms 16 and 17 will be in the same straight line, inwhich position they will remain without being secured and hold the doorin its upper position while open. As the door swings open the arm 17turns in the socketin hinge projection 18 on 'the jamb. The set-screws2O and 2l in the lower arm of the crane are adjusted so as to engageagainst the outer face of the door and hold it in position, so that whenthe upper v end is in contact with arm 11 the lower end will be swungfar enough inward to enter the j amb at the lower end when the door isswung inward. 1 When it is desired to close the vault or safe, the dooris simply swunginto position until it assumes the position shown in Fig.5, when by rotating wheel 28 the extended position of the knuckle-jointis changed to its shorter position and the door is allowed to drop ontothe lower j amb or threshold, and, striking first on the outside, isthrown inward by its own weight into closed position at the top. Thelocking-bolts may then be operated in securing the door in lockedposition. l

l It will be understood that the screw-bolts 3l perform the same officefor the bottom of the door .that the tongue and groove do the sidesviz.,prevent Wedging of the door.

It is evident that many other mechanisms for raising and operatinga doorsubstantially in the same way and to the same end asl the mechanismhereinbefore described may be used, and I do not intend to limit myselfto this particular mechanism, although I consider this the best formthat I have yet used for accomplishing this purpose.

What I claim as new, and desire to secure by Letters Patent, is-

1.. A safe or vault door having tongues or proj ections extendingin theplane of thedoor on a portion of its periphery and tongues orVprojections extending at right angles to the plane of the door on aportion of its periphery, in combination with a jam'b to receive thedoor and tongues or projections, and a hinged crane for carrying andmoving the door to disengage it from the jamb, substantially as setforth'.

2. The combination, With a safe Vor vault door ladapted to be receivedin a janib having down wardly-projecting flanges or projections on itslower end, of a jamb to receive the door, having corresponding grooves`or recesses to receive the 4iianges or projections, substantially asset forth.

3. The combination .of a safe or vault .door

having a tongue or projection extending in the plane of the .door at itslower end, the tongue or projection extending at right angles to theplane of the door at the top, the jamb having suitable grooves orrecesses for for;

receiving the tongues or projections of the d l or vault door, .of acrane, a connecting-link between the `door and crane, and mechanism forraising the door, operating through the connecting-link,substantially'as set forth.

6. The combination, in a safe or vault door, of a suspending-crane, aconnection between the crane and safe-door, mechanism for raising thecrane vertically, and a projection from the crane adapted to engage theface .of the door at the bottom, substantially as and for the purposesset forth.

7. The combination, with a safe or vault door, of a hinged crane on theoutside .of the door, having an arm projecting across the face of thedoor adjacent to the 'top and an arm projecting across the face of thedoor adjacent IIO to thebottom, aconnection between the upper arm andthe safe-door, a projection on the lower arm adapted to engage againstthe face of the door, and mechanism for raising the crane, substantiallyas set forth.

8. The combination, with a safe or vault door, of a crane capable ofvertical movement, a vibrating connection between the door and crane,and a knuckle -joint for raising the crane, substantially as set forth.

9. The combination, with a safe or vault door, of a screw-threadedlocking-bolt, a screwthreaded opening in the bolt-bar, through whichthel locking-bolt projects, a screwthreaded opening in the jamb toreceive the projected end of the bolt, andabolt-throw bar connected tothe bolt to permit the rotation thereof, but to move laterally with thebolt, substantially as set forth.

10. The combination, with a safe or vault door, of a swinging crane onthe outside of the door, having an arm projecting across thetop of thedoor, and a projecting arm projecting across the bottom of the door, theconnectinglink between the upper arm and the door, a projection from thelower arm adapted to engage the face of the door, a projection on thecrane, a projection on the jamb, pivoted levers forming a knuckle-jointextending between said projections, and a hand-wheel and gearing foroperating the knuckle-joint in raising the crane, substantially as setforth.

11. The combination, with a safe or vault door having projections at thebottom, of a j amb having recesses at the bottom to receive theprojections, and mechanism engaging the door to remove the projectionsfrom the recesses and carry the door open, substantially as set forth.

In witness whereof I have aflixecl my signature in presence of twowitnesses.
